I(CLES-220) This invention relates to improvements in car pullers and hasamong other objects 'to provide a new and improved device of the classdescribed of a novel, simplified, efficient and compact construction,operated and controlled in a new and improved manner, which device isparticularly adapted for use with and to be driven by a conveyor of theshaker or jigging type.

An application, Serial No. 669,928, filed May 8, 1933, by William E.Goodman, shows a device of the general type disclosed in my presentinvention. The device of my invention diiers from the aforesaid priorapplication in certain details of arrangement and the specific means fortransferring the motion of the shaker conveyor to the winding drum.

My invention may be more clearly understood with reference to theaccompanying drawings wherein:

Figure 5 is an enlarged detail sectional view of one of the rollers forsupporting the conveyor trough. k

Like reference characters refer to like parts throughout the variousfigures.

Referring now in particular to the embodiment of my inventionillustrated in the drawings, a shaker conveyor pan line is providedwhich includes a reciprocably movable conveyor pan 10. The pan line isreciprocably drivenby suitable conveyor drive mechanism in a manner well`known to those skilled in the art so that material such as coal may bemoved therealong in one direction for discharge into mine cars or othersuitable material receiving means.r As herein shown, the conveyor pan 10is so arranged and supported as to discharge material into suitable minecars 11 on a track 12.

With reference now in particular to the means for moving the cars 11along the track 12 at a controlled rate beneath the discharge end of thein and several novel features of my invention, a car puller, drivenbythe conveyor pan 10 and generally indicated by reference character 13,is

provided. The car puller 13 includes a shoe 14,

which is herein shown as being arelatively flat plate of a substantiallyrectangular outline having upturned ends and being adapted to krest onthe ground or mine bottom. The shoe 14 is adapted to be held in positionon the bottom by p p means of screw jacks 15, `15 of an ordinaryconstruction interposed between said shoe and the mine roof and havingtheir lower ends resting `in suitable recesses formed in said shoe (notconveyor panl l0 as `material is discharged therei I reciprocablemovement with respect thereto in various elevations with respect to theground to accommodate the discharge end of said trough to variousheights of mine cars and conditions of loading.

A pair of support members 19, 19 are adjustably secured to the crossmember 16 and extend upwardly therefrom. Each of the support members 19forms a support means for an anti-friction roller device 20 securedthereto by means of a stud 21 formed integral with the inner race ofsaid roller device. The` anti-friction roller devices 20, 20 arearranged to engage the under side of the conveyor pan 10 for supportingsaid conveyor pan for reciprocable movement with respect to the crossmember 16. y

The shoe 14 is providedvfwith a pair of parallel spaced upstandingsupport members 22, 22 which provide a. support for a shaft 23 adjacentits ends. The shaft 23, as herein shown, is held from rotation by meansof a plate 25a engaging a suitable groove formed in said shaft and is soarranged as to extend longitudinally of the conveyor pan 10. A windingdrum 24 is freely mounted on the shaft 23 for rotation with respectthereto. The winding drum 24 is provided with an annular flanged portion26 extending perpendicular to one of its flanges, which annular angedportion has ratchet teeth 27, 27 cut integral therewith. An annularanged portion 28 extends outwardly from the opposite flange of thewinding drum 24 and has ratchet teeth 29 formed integral with its Outerperiphery. The ratchet teeth 27 are )member 33 adapted to be engaged bypawl 30 pivotally connected to one lever arm 32 of a bell crank member33. The bell crank member 33 is journaled on the shaft 23 for pivotalmovement with respect thereto in a suitable manner so that upon rockingmovement of said bell crank member', engagement of the pawl 30 with theratchet teeth 37 will impart rotational movement to the winding drum 24when the lever arm 32 moves in one direction. The ratchet teeth areadapted to be engaged by a dog 34 pivotally carried `by an upstandingsupport member 35 stationary With respect to said winding drum so thatengagement of the dog 34`With the ratchet teeth 29 will prevent rotationof the winding drum .24

in an opposite direction to which it is normally driven by the pawl 30.

A leverV arm 36 ofthe 'bell crank member 33 extends therefrom in adirection towardwiihe central portion of the cross member 16. An arm y37 extends downwardlyfromV thelever arm 36 and has a tension member,such asa coil spring 38 interposed between 4the end of said armand theframe for supporting the winding drum 24. lThe coil spring 3S is soarrangedlas to move the bell crank member 33' in a direction opposite towhich it moves when engaging the' pawl`v 30 with the ratchet teeth 29and rotating the wind-` ing drum 24. 4 r

A shield 40, herein shown as being formed in theshape of la segment of acircle and having Van outwardly extending flange 41 `.formed integralftherewith, Ais freely carried on the shaft 23 for pivotal vmovementwith respect thereto Vand i's 'disposed yadjacent fthe outer side of thebelfl crank The flange 41 on -th'e shield 40 acts as ja cam and is'adapted to be engaged by a 'roller 42A on the outer end -of the pawl 30so that said rol-ler may 'engage and ride along the outer periphery ofthe flange -41 and hold the ipawl 30 in va disengagedA position withlrespect to the ratchet teeth 29. A tension spring 43V is Vconnected tothe end vof the shield y opposite `the vfla-nge 4l and is interposedbetween shield Aand lthe frame "of the wind-ing drum 24 in such a'manner thatV said spring will tendl to 4engage said shield with theroller 42. A flexiblemember 44 is "secured to an arm 44a 'extendingoutwardly.

from the'shield 40 in a suitable manner for moving said shield againstthe tension spring 43 and permitting the roller 42 yto fbe disengagedfrom the `flange I41. Thus when it is desired lto rotate 'the drum 24and the bell crank mem-ber k33 is -reciprocably driven;l the applicationof tension '1 on the "exible member 44 will pivot the shield 40 aboutthe axis 'of the shaft '23, which will permit the roller '42 to -be'disengaged lfrom `the ilange 41. The number of teeth whichthe pawl /30may move the'winding drum 24 per stroke of thebell 'crank member 33 isthus controlled by movement Yof the 'shield 40, effected by tension onthe flexible member v44 so that the pawl '30 may move said winding druma distance -of one, two, three or more teeth per stroke of said bellcrank member depending upon the length `of stroke of said bell crankmember. In order toV s top rotation of the winding drum 24, tension onthe flexible member 44 is released whichy permits the roller 42 toengage and ride along the flange 41 and 'holds the pawl 30 inadisengaged vposition with respect lto the ratchet teeth 29.

Referring now in particular to the means lfor vreciprocably moving thebell crank member 33 upon reciprocable vmovement of the conveyor pan 10and several vother of the novelfeaturesfof `my ends of said universalcouplings. .is thus capable yof adjustment to take care of invention,the lever arm 36 of said bell crank member has a forked outer end whichis provided with a plurality of apertures 45, 46 and 47, spaced inwardlyfrom the outer end thereof in the order enumerated. A bell crank member48 is journaled on the cross member 16 lfor pivotal movement withrespect thereto between the brackets 19, 19. A link 49 is pivotallyconnected between one lever arm 50 of the bell crank member 48 and oneof the apertures 45, 46 or 47 depending upon the length of stroke of theconveyor pan 10. f

The link 49 is herein shown as comprising a universal coupling 5lpivotally connected to the lever arm 36, la universal coupling 52pivotally connected tothe .lever arm 59, a threaded rod 53 connectingsaid couplings together and held from movement with respect thereto bymeans of nuts 54, 54thr-eaded thereon and abutting the inner The link 49varying positions of adjustment of the cross `member 1'6 with respect totheground.

A link `55 is providedfor connecting another lever .arm 56 of the bellcrank member 48 With-T400 vthe conveyor trough 1'0. The link 55 includesa 16, a threaded rod .60 -adjustably kconnecting said olevises togetherand nuts 6l, 61 for locking said clevises in various positions ofadjustment with respect .to each other along said rod. The length vofthe connecting link 55 may thus be adjusted im@ v to take care of varymglengths of `pan lines or positions of the pan I0 with respect to thecross member 16.

A flexible cable 62 is adapted to be connected -to the winding drum 24and may be trained there- 11:15 from :around a suitable sheave 63 to `aycoupler of one of the cars V11. Thus when tension is applied to theflexible member 49, the winding drum 24 `may be driven bythe 4conveyortrough l0, the amount of `tension 4applied `to said flex- 2.1112@ iblemember is increased the speed of rotation -of said winding drum may beincreased and when tension is released from said flexible member4'rotation ofsaid winding drum may cease.

1t may thus be seen that a car puller of atggg new and improvedconstruction' 'has been Tprovided wherein the winding drum is adapted tobe lrotatably driven by means of a rshaker conveyor pan line, which oarpuller is arranged -in such a manner that the 'conveyor trough issupported 3U on the frame work :which vsupports the car puller and holdsit from movement with respect to the ground, land that the device of Vmyinvention is so arranged that reciprocablamovcment of the conveyortrough is transferred into rotational movement through a simple andnovel vsystem of links and levers in an improved and emcient manner.

While I have herein shown and described one form in which my inventionmay be embodied, it 1 will be understood that the arrangement of thevarious parts and the construction thereof may be altered or changedwithout departing from the spirit and scope thereof.
